Abstract
Electrical continuity between the terminals of a multi-contact electrical connector and the cores of insulated leads that have been connected thereto, is tested for by engaging a respective electrical test probe with each of the terminals and using a multiplexer to connect each test probe in turn to a continuity testing circuit, under the control of a computer. Following the continuity test, a bank of analog switches also controlled by the computer is used to apply short circuit test electrical potential to energize selected terminals, and the presence of the test potential on adjacent unenergized terminals is tested for by the computer, to detect short circuiting between the terminals.
